When a PHP exception is thrown, the PHP runtime looks for a catch statement that can handle that type of exception.
If one is not found, the exception is handed to the global exception handler that we will also cover in this article.
// run your code here
//code to handle the exception
//optional code that always runs
The following keywords are used for PHP exception handling.
Using the first person in assignment is a NO but, not a strict NO. Confused when is it ok to use first person in university assignment Writing?

Handling errors in PHP is almost the same as handling errors in other programming languages.
When we say error handling we are referring to the process of catching errors produced by your program which needs proper action.
It is used to change the usual way of handling code execution of a specific error condition when it occurs.
In this way, exception handling provides a better technique over error handling.

try {
// Some code
} catch (Exception $e) {
echo ‘Message: ‘ . $e->getMessage();
}

3. array_key_exists() vs in_array()
If you are using array_key_exists() instead of in_array(), believe it or not, it is a good choice you made. array_key_exists() is much faster than in_array().
array_key_exists($key, $array); // ideal
in_array( $key, array_keys( $array ) ) // This creates an array of keys from the given array first, which makes it much slower than array_key_exists()
4. unserialize() vs json_decode()
Try to avoid using unserialize, use json_decode instead. The main difference between the two is the fact that unserialize is much more dangerous if used for data received from the network.
